LOGGING-GAR BUNK.

Specification of Letters Patent.

Patented Dec. 23, 1913.

To all whom it may concern.-

Be it known that I, WILLARD HOUGI-ITON, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Logging-Car Bunks, of which the following is aspecification.

This invention relates to bunks for logging-cars; and its object is the provision of a simple and inexpensively constructed bunk over which logs may be longitudinally shifted when loading a car without injury to the bunk and with little likelihood of the bunk being dislodged from the car by being encountered by protuberances on the logs.

lVith these ends in view the invention consists in the novel construction and adaptation of devices, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a carbody with the present invention applied thereto. Fig. 2 is a similar view with the bunk shown incomplete, to more clearly illustrate the manner of assembly of the bunk parts.

Referring to the drawings, the numeral 5 designates the platform or deck of a flatcar comprising planks secured to longitudinal timbers 6, as customary.

According to the present invention, a bunk is comprised of a centrally disposed beam 7 extending .transversely of the car and which is protected upon opposite sides by glacis pieces 8 which are rigidly secured thereto and having inclined outer faces 9 at opposite sides.

The beam 7 is, by preference, composed of a plurality of superposed boards, as 10, whereof the lower one is nailed or otherwise rigidly secured directly to the deck planking of the car, and the boards above are successively nailed to the ones next below.

As illustrated,the beam is formed with sloping side surfaces 11 and the referred to glacis pieces are made of plates or boards having parallel surfaces. The boards constituting the glacis pieces are disposed to have the grain extend up and down or in the direction of the slope of the adjacent side surface of the beam, so that end wood, as it is called, is presented at the upper ends 12 of the various pieces. The lower ends 13 of the glacis pieces are beveled to fit against the car deck, while the upper ends of-the glacis pieces are beveled to present surfaces which coincide approximately with the plane of the upper surface 14 of the beam 7. As illustrated, the glacis pieces at each side of the beam are shown as composed of a number of layers, the pieces of each layer being desirably disposed to have their joints intermediate the joints of the juxtaposed layers.

Where the glacis pieces are comprised of a plurality of layers, the ones next to the beam would be first nailed to the latter and to the deck, the second layer nailed to the first layer and to the deck, and so on.

The operation of the bunk is obvious.

Among its advantages are, first, that by making the beam of layers the same is more readily and reliably secured to the car deck by a suitable distribution of the fastening nails, or equivalent devices, and also to the supplementary securement through the office of the glacis pieces which are secured both to the beam and to the car deck; and secondly, in the principal office of the glacis pieces which present sloping surfaces to ward upwardly logs, or the like, when the same are shifted lengthwise to equalize the load with respect to a car, to prevent the ends of the logs or projecting knots thereon from exerting an end thrust which would tend to break or tear the bunk from the car-deck.

What I claim, is

1. A car-bunk formed of a beam having sloping side surfaces comprised of a plurality of layers, and glacis pieces secured to the beam against the side surfaces and present-ing sloping outer surfaces at opposite sides of the bunk.

2. Incombination with a car-deck, of a bunk rigidly secured to said deck, said bunk being provided upon opposite sides with sloping surfaces disposed in upwardly con verging planes.

3. In combination with a car-deck, of a bunk comprising a beam extending transversely of the deck and rigidly secured thereto, and glacis pieces secured to the beam, and presenting sloping outer surfaces at opposite sides of the bunk.

4. In combination with a car-deck, of a bunk comprising a beam extending transversely of the deck and rigidly secured thereto, and glacis pieces secured both to the beam and said deck and presenting sloping outer surfaces at opposite sides of the bunk.

5. In combination with a car-deck, of a bunk comprising a centrally disposed beam having upwardly converging side faces, and glacis pieces juxtaposed with said side faces and having their upper ends beveled to correspond with the upper surface of the aforesaid beam.

6. In combination with a cardeck, of a bunk comprising a centrally disposed beam v having upwardly converging side faces, and

glacis pieces juxtaposed with said side faces and having their upper and lower ends beveled to respectively correspond with the upper and lower surfaces of the aforesaid beam.
